摘要
首先论述做为热拌沥青混合料水稳定性检验方法的浸水马歇尔试验仍有待于进一步改进;接着分析了国外关于沥青路面渗透系数的研究情况,以及测定路面渗透系数对防止沥青混凝土路面出现早期水损害的重要性;最后就如何防止高速公路沥青混凝土路面出现早期水损害在路面压实度方面提出建议。
First, the paper discusses that Marshall immersion trial, as an examinating method for water stability of hot - mixed asphalt mix, needs still further improvement, then analyzes investigation of coefficient of water permeability of asphalt pavement abroad, at last makes suggestions in pavement compactness on prevention of early water injury of freeway asphalt concrete pavement.
